RAILWAY SYSTEM.

Application filed April 6, 1915.

T 0 all whom it may concern:

Be it known that I, i/VALTER S. KELLEY, a citizen of the United States, residing in Brookline, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Railway Systems, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings repre senting like parts.

This invention relates to a railway system, especially designed and adapted for use in large cities having a plurality of trunk or other lines which enter the city from different directions.

The present invention has for its object to provide a system by means of which a plurality of trunk or other lines may be connected together, so as to form part of one complete system, whereby all the lines of track may be interconnected or may be converted into looped circuits or both at a minimum expense and with a minimum number of switches. Provision is also made for handling diflerent kinds of traffic, as will be described. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure l is a diagrammatic view of a railway system embodying this invention, and Fig. 2, a sectional view of a union station having the arrangement of tracks preferred by me, the section being'taken on the line 22, Fig. 1.

In the present instance, I have illustrated a railway system embodying the invention in which four trunk lines, such, for instance, as four complete systems, as may now be found in large cities, are connected together to form a unitary system.

The four trunk systems are marked a, 7), c, d, and each comprises four tracks 10, 12, 18, 14, each track being represented as a single line in Fig. 1. The tracks 10, 12, may be considered the outward tracks of the trunk lines, and the tracks 13, 14, the inward tracks thereof.

The tracks 10, 12, 13, 14, of each of the trunk lines a, Z), c and 0?, are connected preferably with a plurality of tracks in the form of circles of difierent diameters and indicated in Fig. 1 by single lines 15, 16, 17, some of which may and preferably will be located on different levels, as represented in Fig. 2, wherein the circular track 15 of Specification of Letters Patent.

largest diameter and the circular track 17 of smallest diameter are shown on substantially the same level, and the intermediate circular track 16 is shown on a higher level. The circular tracks may be located above the surface of the street or they may be located below the surface thereof, or some above and others below said street surface.

In the arrangement shown in Fig. 2, the intermediate circular track 16 is represented at the higher level and the circular tracks 15, 17 at a lower level. Connection with these circular tracks of the tracks of the trunk lines a, b, c and d, may be had by suitable subways, and in Fig. 2, two subways are indicated by the dotted lines 20, 21, through which the tracks of the trunk line I) connect with the circular tracks 15, 16, and a branch subway from the subway 21 is indicated by the dotted lines 22, through which tracks from the trunk line b are connected with the circular track 17. It will be understood, that similar subways are provided for connection of the other trunk lines 0, cl and a with the circular tracks 15,16,17.

Provision is also made for handling passengers discharged from the trains, and for this purpose, circular platforms 23, 24, 25 are provided-within the inner circumference of the circular tracks 15, 16 and 17. Also access from one level to the other may be had by means of escalators or Stairways 26, 27, 28, and from the platform of the track 16 to the street level 29.

The circular tracks may be located within a union station, and the operation of the system may be readily understood by tracing the course of a train which enters the station from one trunk line.

Assume that a train is an express train and enters the station from the trunk line 0 on track 13. The train passes from track 13 to the circular track 15 and proceeding in the direction of arrow 30, Fig. 1, it can pass out onto track 12 of trunk line cl, a or b as the case may be, depending upon which one of the trunk lines the destination of the train is located. If the train is a through accommodation, it enters the station on track 14 and proceeds to the circular track 16, from which it passes by track 10 of any one of the trunk lines d, a and b, and if the train is a local one, it enters the station by track 14 to the circular track 17 and proceeds to track 10 of any one of the trunk lines d, a and b. If the local is a loop train, it enters on track 14 to the circular track 17 and after discharging its passengers, completes the loop on track 17 and returns to trunk line on the outgoing track of said trunk line. In the same manner, the trains from any of the other trunk lines can proceed to their destinations on any of the trunk lines. It will thus be seen that all the through express trains may use the circular track 15, all the accommodations or local express trains may use the circular track 16, and all the local trains may use the circular track 17, without interfering with one another, and these circular tracks can be used for freight as well as for passenger business, and if desired and the demand warrants it, an additional circular track can be installed and connected with the express tracks of the trunk lines for express freight service.

It will be observed that all the trains proceed in one and the same direction.

By the system above described, grade crossings may be avoided, the switching arrangements reduced to a minimum, and a maximum amount of traific handled at the least possible expense and in the least time.

If desired, spur tracks can be tapped off from any quadrant of any of the circular tracks for storage of cars.

In the present instance, I have illustrated four systems or trunk lines as connected with three circular tracks, but it is not desired to limit the invention to the particular number of trunk lines or circular tracks herein shown, or to theparticular classification of trafiic herein described.

By the term circular as used in the claims, it is desired to be understood that the invention is not restricted to the exact geometrical form of a circle, but is desi ned to include a closed track circuit.

I claim:

1. In a railway system, in combination, a plurality of circular tracks, and a plurality of trunk lines of tracks extended in different directions and having an ingoing track and an outgoing track connected to said circular tracks, one of said trunk lines being directly connected with a plurality of the circular tracks.

2. In a railway system, a plurality of lines of track each having a plurality of inward and outward tracks, and a plurality of circular tracks with one of which one set of said inward and outward tracks of said lines is directly connected, and with another of which another set of said inward and outward tracks of said lines is directly connected.

3. In a railway system, in combination, a plurality of inward and outward lines of tracks extended in different directions, and a plurality of circular tracks located at different levels and with each of which the ingoing and outgoing tracks of a plurality of lines connect.

4. In a railway system, in combination, a plurality of circular tracks, and a plurality of lines of tracks extended in different directions and connected with said circular tracks, one of said lines having a plurality of inward and outward tracks connected directly with separate circular tracks.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

. I VALTER S. KELLEY.
